# Roblox with Intel Core i5-12400F + NVIDIA GeForce RTX 4070

The Intel Core i5-12400F paired with the NVIDIA GeForce RTX 4070 ranks 486th out of 1,800 tested combos in Roblox, placing it in the top 27% of all system configurations. This is a strong result for a mid-range desktop pairing, with the CPU holding a 77th percentile ranking among all processors and the GPU sitting at the 81st percentile among all graphics cards. The combination delivers exceptionally high frame rates across all tested resolutions, with the lowest average result still exceeding 120 FPS, indicating that this system is far from being constrained by hardware limitations in this sandbox title.

How This Combo Ranks

The combo's 486th position out of 1,800 tested configurations reflects a system that sits comfortably in the upper tier of Roblox performance. The Intel Core i5-12400F's average benchmark score of 19,221 places it in a tight cluster with several rivals: it trails the AMD Ryzen 5 7533HS by 0.7% (that chip scores 19,364), but leads the Intel Core i7-8700K by 0.1% (19,210) and the Intel Core i5-1335U by 0.3% (19,167). The margin against the AMD EPYC 7773X is more substantial at 1.3% (18,979). This grouping shows that the 6-core, 12-thread Alder Lake processor delivers competitive compute performance against both older desktop flagships and newer mobile parts, though the differences are minimal in synthetic workloads.

On the graphics side, the RTX 4070's average benchmark score of 37,283 places it near the AMD Radeon RX Vega 56 (37,507, 0.6% higher) and the NVIDIA GeForce MX570 A (38,008, 1.9% higher). Interestingly, the RTX 4070 outperforms the NVIDIA GeForce RTX 4080 Mobile by 2.2% (that part scores 38,135 lower at 38,135 versus the desktop card's 37,283 — wait, the delta is listed as -2.2% meaning the RTX 4070 is 2.2% behind the RTX 4080 Mobile, which scores 38,135). The closest competitor below is the AMD Radeon RX 5300M at 36,371, which the RTX 4070 leads by 2.5%. These tight margins in synthetic benchmarks belie the RTX 4070's substantial advantage in real-world gaming scenarios, particularly at higher resolutions where its 12 GB of GDDR6X memory and 504.2 GB/s bandwidth come into play.

GPU Role

The RTX 4070's specifications directly explain the exceptional frame rates observed in Roblox. With 12 GB of GDDR6X memory on a 192-bit bus delivering 504.2 GB/s of bandwidth, the card has ample headroom for this game's relatively modest texture and geometry demands. The GPU's boost clock of 2475 MHz (up from a 1920 MHz base) allows it to sustain high throughput in lighter workloads, and its 5,888 shading units, 184 texture mapping units, and 64 raster output pipelines provide substantial raw compute capacity.

The card's 29.15 TFLOPS of FP32 performance and 158.4 GPixel/s pixel rate are far beyond what Roblox requires even at maximum settings. The 46 ray tracing cores and 184 tensor cores are present but largely idle in this title, as Roblox does not heavily utilize these features. The GPU's 200 W TDP and dual-slot form factor indicate a power-efficient design that can maintain boost clocks without thermal throttling, which is crucial for sustaining the high frame rates seen in the measured data. The 1x 16-pin power connector and 550 W suggested PSU requirement are modest for a card in this performance class.

Resolution Scaling

The measured FPS data reveals a clear pattern: performance scales dramatically with resolution, and the system remains GPU-bound only at the highest settings. From 1080p to 1440p, average frame rates at High settings drop from 404.6 FPS to 269.2 FPS, a 33.5% reduction. Moving from 1440p to 4K at High settings further reduces performance from 269.2 FPS to 150.5 FPS, another 44.1% drop. This scaling behavior indicates that at 1080p, the CPU is likely the limiting factor, as the frame rates exceed what most displays can even show, while at 4K the GPU's workload becomes more significant.

The pattern across all settings reinforces this interpretation. At Low settings, the system produces 502.2 FPS at 1080p, 334.4 FPS at 1440p, and 190.3 FPS at 4K. The 1080p result is extraordinarily high, suggesting that the i5-12400F's 6 cores and 12 threads, with a boost clock of 4.40 GHz, are capable of feeding the GPU with enough draw calls to reach frame rates that are essentially display-limited territory. At Ultra settings, the gap narrows: 326.2 FPS at 1080p, 221.2 FPS at 1440p, and 122.8 FPS at 4K. The fact that 4K Ultra still exceeds 120 FPS demonstrates that this combination has no trouble maintaining smooth gameplay in Roblox, regardless of resolution or quality preset.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates across all settings. Low settings produce an average of 502.2 FPS, Medium achieves 457.2 FPS, High reaches 404.6 FPS, and Ultra drops to 326.2 FPS. The difference between Low and Ultra at 1080p is 176 FPS, a 35% reduction, indicating that the quality presets have a meaningful impact on performance even at this resolution. The progression from Low to Medium to High to Ultra shows diminishing returns in terms of visual quality per frame rate cost, with the largest single-step drop occurring between Medium and High (52.6 FPS).

Moving to 2560x1440, the frame rates remain exceptionally high but show the expected resolution penalty. Low settings average 334.4 FPS, Medium hits 303.2 FPS, High produces 269.2 FPS, and Ultra drops to 221.2 FPS. The gap between Low and Ultra narrows to 113.2 FPS (33.8% reduction), slightly less than at 1080p. This suggests that at 1440p, the GPU is becoming more of a factor, but the RTX 4070 still has substantial headroom. The 1440p results are particularly notable for competitive play, as even Ultra settings maintain an average above 220 FPS, comfortably exceeding the refresh rates of most high-end gaming monitors.

At 3840x2160, performance remains strong but begins to show the GPU's workload more clearly. Low settings average 190.3 FPS, Medium reaches 173.1 FPS, High produces 150.5 FPS, and Ultra drops to 122.8 FPS. The spread between Low and Ultra is 67.5 FPS (35.5%), similar to the 1440p scaling. Even at 4K Ultra, the system maintains an average above 120 FPS, which is remarkable for a game that is typically considered CPU-bound. The 4K results demonstrate that the RTX 4070's 12 GB memory buffer and 504.2 GB/s bandwidth are sufficient for Roblox's needs at the highest resolution, with no signs of memory capacity or bandwidth constraints.
